Now I know I am a PERL "novice" !!
Thank you for the "wisdom" graff.
I have updated my code so that the original stuff I had (data extraction from SQL Server using "Win32::SqlServer") can be used by the code you kindly supplied. I think that it's a excellent base but after checking the result set I think that perhaps I did not do a good job of describing some "irregularities" in the data set.
For example, the text "A1-910-ES-002B" can be found as a parent to "A1-910-ES-002B-16" (the actual record is)
A1-910-ES-002B-16|A1-910-ES-002B (pipe symbol is the delimiter).
Unfortunately, the text "A1-910-ES-002B" is also found in the child number "A1-910-ES-002B-17", which has a parent of "A1-910-ES-002B" (full record is)
A1-910-ES-002B-17|A1-910-ES-002B
I have a sneaking suspicion that the grep command is matching not only the text in isolation but any line that has that text in it.
